ADAPTER FOB SMOTH-FACED FAUCETS.

Application led June 18,

The present invention relates to meansfor connecting a pipe or hose to a smoothfaced faucet.

Most sinks in kitchens and tubs in batha rooms are provided with smooth-faced faucets. It is often desirable to connect these faucets to a hose whereby machines, such as clothes or dish washing machines may be hlled fromthe sink faucet or whereby 4a lo spray nozzle may be used from the bath tub faucet. These smooth-faced faucets have no standard design, the mouths thereon varying in shape with the different manufacturers thereof. Accordingly, it is difficult 1a and often impossible to connect a pipe or hose to the smooth-faced faucet without leakage.

The object of the present invention is to rovide means for connecting a i e or ose to any kind of a smooth-face aucct whereby the connection may be made in a reliable and certain manner.

To the accomplishment of this object, an such others as ma hereinafter appear, the various features o the present invention relate to certain devices, constructions and arrangements of arts as fully set forth hereinafter, the advantages of which will he readily understood by those skilled in the art... 4

The various features of the present invention will be readily understood from l an ins ection of the accompan ing draw: ings il ustrating the best form of, the invention at present known to the inventor, in which,

Figure 1 is an elevation showing a hose connected to a' smooth-faced faucet;

Fig. 4 is a sectional elevation on the line 4-4, Fig. 2. s

The drawings illustrate a hose 5 connected to a smooth-faced faucetv 6. To this end an ada ter 7 (Fi 3) is removably secured tot e smoothaced faucet 6. As shown the adapter 7 com rises a shell 8 the interior of which is slightly frusto-conical in formation having on its smaller base 9 an inturned lip 10 (Fig. 4). The eriphery of the adapter 7 near its larger lliase 11 carries three screws 12, two of which are slotted and one of which is provided with a lill 192. Serial No. 116,495.

finger head. By means of these screws 12 the adapter 7 is removably secured tothe smooth-faced faucet 6. y

Within the shell 8 the adapter carries a perforated rubber washer 13 provided with an annular shoulder 14 which, when the adapter is not in use, rests upon the inturned lip 10. Arranged on top of the washer 13 is a second perforated washer 15. The washer 15 has a greaterdegree of elasticity than the washer 13 being made preferably of sponge rubber.

The adapter 7 is provided with external screw threads 16 which receive internal screw threads 17 on a coupling 18 provided with an internal shoulder 19. The coupling 18 carries the hose 5.

To make the connection the ada ter 7 is first secured to the smooth-faced aucet 6. The coupling 18 is then screwed on to the threads 16. This causes the shoulder 19 to lift the washer 13 u wards within the shell 8 thus compressing t 1e sponge rubber 15 between the mouth 20 of the faucet and the washer 13. During its compressing movement the washer 15 automatically ada ts itself to the shape of the mouth 20. Wijth this construction the washer 13 revents leakage around the shoulder 19 w ile lthe washer 15 prevents leaka e around the mouth 20 notwithstanding t e shape thereof. While the drawings illustrate a mouth 20 which is normal to the direction of `flow of the water therethrough it must be understood that in many faucets the mouths are oifset from a normal position. No matter what shape the mouth may take the sponge rubber 15 will automatlcally seat itself thereby adapting itself to the shape of the mouth.

When the coupling 18 is unscrewed from the adapter 7 the compressed washer 15 re-I turns to its normal expanded condition thus forcing the return of the washer 13 to its original position with the shoulder 14 resting on the lip 10.

In securing the adapter 7 to the faucet 6 and also in removing the adapter therefrom' it is only necessary to mani ulate the screw provided with the head. T e slotted screws project inwardly above the washer 15 thus preventing its accidental dropping from the ada ter.

It wi be clear to those skilled in the art,

and with the general objects of the present invention' in view, that 'changes may be `made in the details of structure, the described and illustrated embodiment thereof being intended as an exploitation of its underlying essentials the features whereof are definitely stated in their true scope in i the claims herewith.

What is claimed as new, is:

l. An adapter for use in connecting a pipe or hose to a smooth-faced faucet comprlsin a shell having on one face an inturne lip, a rubber washer having an annular shoulder arranged to rest upon the lip, and a second Washer of rubber substan-
